Introducing MIRA Pico SeriesTM Middle Infrared Laser-‐Based Gas Analyzers
Next Generation Gas Analyzers Introducing the new MIRA Pico Series portable middle infrared laser-‐based gas analyzers from Aeris Technologies, Inc. MIRA gas analyzers utilize simple and robust direct absorption spectroscopy using high resolution tunable lasers, enabling target species to be measured in real-‐time with sub-‐ppb sensitivity, ppb-‐level accuracy, and high specificity. MIRA Pico Series analyzers provide performance levels previously only achieved in much larger and higher power consumption portable analyzers. Species accessible with the MIRA platform include:
• Greenhouse gases: CO2, CH4, N2O, H2O • Natural Gas: CH4, C2H6 • Pollutants: CO, H2CO
Core Technologies MIRA series analyzers combine state-‐of-‐the-‐art electronics, solid state laser sources, and Aeris’ unique multipass cell technology to achieve sub-‐ppb sensitivity and ppb level accuracy in an ultraportable, low power consumption package. MIRA’s single board computer efficiently controls all critical analyzer functions, with industry-‐lowest power consumption. The proprietary sensor engine used in every MIRA analyzer uniquely achieves a long absorption path length in an extremely small volume, providing ultra-‐high sensitivity and a fast response time with reduced pumping requirements.
MIRA laser-‐based sensor engine, comprising a fixed, sealed optical bench, integrated laser and detector subassemblies, and ultra-‐compact, 60cc, 13m path length optical multipass cell.

MIRA Pico Series gas analyzers are based on mid-‐infrared absorption spectroscopy, providing high sensitivity and specificity. Compared to near-‐infrared absorption-‐based analyzers currently on the market, MIRA mid-‐infrared analyzers enable the same absorption to be obtained in a much shorter path length. This eliminates the need for fragile, high reflectivity optics in the sensor core, making MIRA analyzers 100x less susceptible to optical contamination than analyzers based on “cavity-‐enhanced” approaches.
Typical CH4 absorption spectrum obtained with the MIRA Pico Series Analyzer. Spectra are obtained at a repetition rate of 1kHz, providing real-‐time concentration as well as dry mole fraction data in cases where water vapor is measured simultaneously.
Typical CH4 precision and long-‐term drift shown over an extended period under typical varying room temperature conditions (few degrees C). This level of stability is sufficient for many field applications.
